To all whom it may concern.- 1 in standards A, forming part of the main Be it known that I, JOHN DOUGHTY, of frame A. The racks D and G are pivotally Philadelphia, in the county of Philadelphia connected by pitmen J and J", respectively, and State of Pennsylvania, have invented a with crank-arms J 2 and J respectively, exnew and Improved Machine for Treating tending in opposite directions and secured on Metal Rods, of which the following is a full, a transversel' -extending shaft J journaled clear, and exact description. in suitable bearings, as plainly illustrated in The object of the invention is to provide a Figs. 1 and new and improved machine for conveniently On the shaft .I is secured a pulley J over 6o 10 and rapidly tempering, cleaning,and straightwhich passes a belt .I, connected with suitening metal rods in a very simple and efiiable machinery, so that rotary motion is given cient manner. to the said pulley J 5 and the shaft 3 to turn The invention consists of certain parts and the crank-arms J and Ji'whereby a reciprodetails, and combinations of the same, as will eating motion is given by the pitmen J and 6 3 :5 be hereinafter described, and then pointed J to the racks D and G, held on the frames out in the claims. 0 and II, respectively, reci n-ocating in the Reference is to be had to the accompanying guideways B and I, respectively. drawings, forminga part of this specification, It will be seen that as the crank-arms J in which similar letters of reference in dieate and J stand in opposite directions one to the 70 corresponding parts in all the figures. other, the racks D and G move in opposite Figure l is a plan view of the improvement. directions, so that the bundle of rods E, en- Fig. is a transverse section of the same on gaged between the racks D and G, is rotated the line 2 2 of Fig. 1, and Fig. 3 is an enlarged without being moved forward or backward, longitudinal section of the same on the line it being understood that the individual rods 75 3 3 of Fig. 1. on the bottom and top of the bundle are en- The improved machine for treating metal gaged by the teeth of the racks D and G. rods is provided with a suitably-constructed Thus when the rack G moves forward in the frame A, supporting longitudinallyextenddirection of the arrow a and at the same ing guidcways B, on which is mounted to retime the raclc D moves backward in the in- 80 3o ciprocate a rack-frame C, supporting a severse direction of the said arrow, then the ries of longitudinally-extending racks I), as bundle of rods E is rotated in the direction plainly illustrated in Figs. 2 and The of the arrow Z), and when the motion of the racks D are arranged parallel one to the other said racks is reversed then the motion of the and are adapted to receive a bundle of rods bundle of rods E is likewise reversed-that 8 3 5 E to be treated, the said rods being held in is, the bundle turns in the inverse direction rings F, which permitthe rods to revolve and ofthe arrow Z). rub one on the other when agitated, as here In order to prevent lateral movement of the inafter more fully described. bundle of rods E, I provide the end plates K The rods E are placed suificiently loose in against which abut the ends of the rods E, 90 c the rings F, so that the lowermost readily the said plates K being held transversely adpass between the teeth of the racks D, it bej ustable on the main frame A, so as to move ing understood that the teeth of the racks the plates K suitable distances apart correregister with each other, so as to hold the spending to the length of the rods under bundle of rods straight and at right angles treatment. The rods E in the bundle are of 9 5 to the racks. The uppermost rods E in the uniform length and consequently are prebundle are adapted to be engaged by the teeth vented from lateral movement by the plates of racks G, preferably arranged directly op- K. A feed-table L extends between the two posits the lower racks D, the said racks G racksD and G, so that the bundle of rods E being held in a frame II, mounted to reciprocan readily be moved over the said feed-table I00 eate in guideways I, connected with each L onto the racks D or removed therefrom at other byeross-bars I and I and fulcrumed at the time the connected guideways I, with the frame 11 and racks G, are swung into an uppermost position, as indicated in dotted lines in Fig. 3, it being understood that the said guideways I swing on the points I as their fulcrum. The individual racks D and G are held transversely adjustable on their frames C and II, respectively, so as to move the said racks in proper position, according to the position of the rings F and the length of the rods.

Now for tempering metal rods, for instance, the rods to be treated and already hardened in the usual manner are taken from the oiltank usually in a crooked state and then mixed with a number of previously-heated rods, after which the rings 1* are slipped over the said rods, and then the bundle thus formed is rolled or pushed over the feed-table L onto the racks l) at the time the racks G are raised, after which the latter are lowered to engage the uppermost rods. The shaft J is then rotated, as previously described, to impart a reciprocating motion to the racks D and Gin opposite directions to agitate the bundle of rods in the manner described. Now it will be seen that by the rubbing of the rods to be treated on the previously-heated rods the oil of the rods from the oil-tank gets on fire by coming in contact with the hot rods, so that the hardened rods are not only annealed but are made straight and kept straight by the other rods. After the rods are properly annealed the racks G are swung upward, the bundle is removed from the racks D and a new one substituted, and the abovedescribed operation is repeated. For cleaning rods in a bundle or bunch they are agi tated by the racks D and G, as above described, and sand, emery or other cleaning material may be fed on the rods while in motion in the machine.

The cleaning material greatly assists in freeing the rods of any impurities adhering to the outer surface. It is understood that the rods on being agitated in the manner described rub one on the other, so as to remove rust or other impurities adhering to their peripheral surface.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 7 1. A machine for treating metal rods, comprising frames havdng racks and adapted to move in opposite directions, the racks being adapted to receive between them the bundle of rods to be treated, means, substantially as described, for imparting a reciprocating motion to the said racks, end plates adapted to engage the ends of the bundle of rods and a feed table extending between the said racks and terminating adjacent to said end plates. substantially as shown and described.

2. A machine for treating metal rods, comprising a frame provided with a rack and mounted to reciprocate in stationary bearings, a second frame provided with a rack and having a reciprocating motion, and pivoted bearings for the said second rack frame. substantially as shown and described.
